I am still in shock. I drew my Utah dream tag, South Bookcliff's Rattlesnake unit for Rocky Mountain Bighorn sheep. starting the prep work now and will be spending every other weekend scouting between now and the Nov.1 opener so excited I'm having a hard time typing!
My experience with desert bighorns tells me that any scouting you do prior to late September/October will only serve to help you familiarize yourself with the area and allow you to look over some the sheep the area has to offer. Once they start to rut they will move constantly and sometimes many miles per day.
You may want to see if you can contact someone with experience in that unit as they may have some insight as to where the rams traditionally gather to rut.
